课程名称：流体力学 课程概述：本课程将应用牛顿流体的基本行为原则，描述并解决特定问题。分析区分流体与固体的基本概念，建立流体颗粒的微分关系，应用质量和力矩守恒原理于流体动力学中，了解流体的静力学、运动学和动力学。 流体力学是研究静止或运动的流体的学科。它传统上应用于渠道、堤坝和水坝系统的设计，泵、压缩机及水和空调系统的管道设计，以及化工厂所需的管道系统。在汽车及亚超音速飞机的空气动力学方面也有广泛应用。此外，流体力学在流量测量设备的发展中扮演重要角色，例如燃气泵计。 虽然这些领域依然至关重要，例如当前对汽车流线型设计和2005年新奥尔良堤坝失效的重视，但流体力学作为一门“高科技”学科，在过去25年中发展了许多令人兴奋的领域。例如，环境与能源问题（如控制油污、大型风力发电机、从海浪中产生能量、建筑物空气动力学、气候与海洋流体力学，以及龙卷风、飓风和海啸等现象）；生物力学（如人工心脏和心脏瓣膜，以及理解血液、关节滑液、呼吸系统、循环系统和泌尿系统的流体力学）；体育（如自行车及其头盔、滑雪板、短跑和游泳服的设计，以及高尔夫、网球和足球的空气动力学）；“智能流体”（如在汽车悬挂系统中优化所有地形条件下的运动的流体层、在战斗时能够“加固”的军事制服，以及用于相机和手机的类人属性的流体镜头）；以及微流体（如用于精准给药）。 该课程适合希望深入了解流体力学基本原理及其应用的学习者。
Apply the basic principles of the behavior of Newtonian fluids, after describing them, to solve specific problems.Analysis of the basic concepts that allow differentiating fluids from solids.Establishment of differential relationships for a fluid particle.Application of the principles of mass and moment conservation in fluid dynamics.Know the statics, kinematics and dynamics of fluidsAs the name implies, fluid mechanics is the study of fluids at rest or in motion. It has traditionally been applied in such areas as the design of canal, levee, and dam systems; the design of pumps, compressors, and piping and ducting used in the water and air conditioning systems of homes and businesses, as well as the piping systems needed in chemical plants; the aerodynamics of automobiles and sub- and supersonic airplanes; and the development of many different flow measurement devices such as gas pump meters.While these are still extremely important areas (witness, for example, the current emphasis on automobile streamlining and the levee failures in New Orleans in 2005), fluid mechanics is truly a "high-tech" or "hot" discipline, and many exciting areas have developed in the last quarter-century. Some examples include environmental and energy issues (e.g., containing oil slicks, large-scale wind turbines, energy generation from ocean waves, the aerodynamics of large buildings, and the fluid mechanics of the atmosphere and ocean and of phenomena such as tornadoes, hurricanes, and tsunamis); biomechanics (e.g., artificial hearts and valves and other organs such as the liver; understanding of the fluid mechanics of blood, synovial fluid in the joints, the respiratory system, the circulatory system, and the urinary system); sport (design of bicycles and bicycle helmets, skis, and sprinting and swimming clothing, and the aerodynamics of the golf, tennis, and soccer ball); "smart fluids" (e.g., in automobile suspension systems to optimize motion under all terrain conditions, military uniforms containing a fluid layer that is "thin" until combat, when it can be "stiffened" to give the soldier strength and protection, and fluid lenses with humanlike properties for use in cameras and cell phones); and microfluids (e.g., for extremely precise administration of medications).
